Food intake of folate, folic acid and other B vitamins with lung cancer risk in a low-income population in the Southeastern United States.

ABSTRACT:

Purpose

We prospectively examined associations of lung cancer risk with food intake of B vitamins involved in one-carbon metabolism and the use of folic acid-containing supplements among a low-income population of black and white adults in the Southeastern US.

Methods

Within the Southern Community Cohort Study, we included 1064 incident lung cancer cases among 68,236 participants aged 40-79 years at study enrollment. Food intake and the use of folic acid-containing supplements were assessed using a validated food frequency questionnaire at study enrollment. Multivariate Cox regression was used to estimate hazards ratios (HRs) and the 95% confidence intervals (CIs).

Results

Folate and/or folic acid intake from food were not associated with lung cancer risk; HRs (95% CI
